CFULA455KB4Y-B0

Overview

The CFULA455KB4Y-B0 is a ceramic bandpass filter manufactured by Murata Electronics, designed for signal conditioning applications. It operates at a center frequency of 455 kHz with a nominal impedance of 1.5 kOhms. The device features a bandwidth of 15 kHz and an insertion loss of 5 dB. It utilizes a through-hole mounting type within a cube package containing three pins. Physical dimensions are specified as 8 mm in length, 7 mm in width, and 7.3 mm in height. The component supports an operating temperature range from -20 °C to +80 °C.

Feature Summary

• Utilizes ceramic construction for stable signal filtering performance
• Designed for through-hole board mount installation
• Provides specific bandpass characteristics at 455 kHz

Applications

• Intermediate frequency (IF) filtering in communication receivers
• Signal conditioning in analog circuitry
• Audio or telemetry signal processing systems

Procurement Notes

Verify current availability status as this component may be subject to end-of-life notices or limited distribution channels. Confirm that the 1.5 kOhm impedance and 455 kHz center frequency align precisely with the target circuit design requirements before procurement. Ensure compatibility with existing PCB footprints for the three-pin through-hole configuration.

Selection Notes

Select this component when a fixed 455 kHz ceramic filter with 1.5 kOhm impedance is required. The 15 kHz bandwidth and 5 dB insertion loss define the selectivity and signal attenuation characteristics. Consider the physical size of 8x7x7.3 mm for spatial constraints on the printed circuit board. Verify thermal stability needs against the -20 °C to +80 °C operating range.

Part Context

This part belongs to Murata's CERAFIL series of ceramic filters. These components are engineered for reliable signal conditioning in electronic equipment. The CFULA suffix typically denotes a specific leaded ceramic filter variant within the broader Murata passive component portfolio.

Replacement Considerations

Direct substitutes must match the 455 kHz center frequency, 1.5 kOhm impedance, and 15 kHz bandwidth. Verify pinout compatibility for the three-lead through-hole package. Check if alternative manufacturers offer equivalent ceramic filters with identical electrical parameters and mechanical dimensions.
